My favorite is Street Parked SF, his photograph and knowledge is impressive, as well as the vehicles he finds.
Next is Portland based Other People's Things. It's astounding what strange unique vehicles persist in the Northwest and OPT displays this wonderfully.
Now we come to NYC based the Automobilist. His style and finds are still great but deffinately third behind his west coast brethern.
And finally, my blog, This Velologist. I have always taken pictures of interesting cars I see but these guys inspired me to make a stylized, frequent go of it so I joined this legion of street parked vehicle documenters. I'm also on Instagram @thisvelologist.
Take a look at these blogs, give 'em a follow and enjoy the regular content that gives you hope for the automotive world.
